             ##### I2C peripheral Extended features  #####
==============================================================================

[..] Comparing to other previous devices, the I2C interface for STM32H7xx
     devices contains the following additional features

     (+) Possibility to disable or enable Analog Noise Filter
     (+) Use of a configured Digital Noise Filter
     (+) Disable or enable wakeup from Stop mode(s)
     (+) Disable or enable Fast Mode Plus

                   ##### How to use this driver #####
==============================================================================
[..] This driver provides functions to configure Noise Filter and Wake Up Feature
  (#) Configure I2C Analog noise filter using the function HAL_I2CEx_ConfigAnalogFilter()
  (#) Configure I2C Digital noise filter using the function HAL_I2CEx_ConfigDigitalFilter()
  (#) Configure the enable or disable of I2C Wake Up Mode using the functions :
        (++) HAL_I2CEx_EnableWakeUp()
        (++) HAL_I2CEx_DisableWakeUp()
  (#) Configure the enable or disable of fast mode plus driving capability using the functions :
        (++) HAL_I2CEx_EnableFastModePlus()
        (++) HAL_I2CEx_DisableFastModePlus()
